Bruce had to beat off competition from Liverpool, Arsenal and Tottenham to secure 18-year-old Ipswich striker Wickham and he believes Sunderland have landed one of the most exciting young prospects in the English game.
The fee for the Wickham could rise to £12m with add-ons, and takes Bruce's summer spending to around £20m.
Bruce said: "The signing of Connor Wickham is a statement of intent by Sunderland. It is a bold signing that shows we are building for the future. There were a lot of top clubs tracking him, but we were the ones who were prepared to meet Ipswich's valuation.
"It is also a testament to our progress as a club that Connor wanted to come here. I am sure he will be a big hit with the fans."
